Quadrupole Magnet On Outer Diameter Surface Gauss
To put it simply, Gauss represents the range of magnetic field lines per square centimetre, emitted by means of a magnet. Other forms of magnets including Samarium-Cobalt have higher heat resistance.
How a magnet behaves when it's employed in closed circuit, including within the application it's intended for has an effect on its general strength. Or, you may have a little magnet with a tall Surface Gauss that will pull less than a bigger magnet with a reduce Surface Gauss. If you've got two different sized magnets with the exact same Surface Gauss, the bigger magnet will be stronger. When you're looking at magnets on the Digi-Key web site you will find a surface gauss strength rating on a lot of the magnets. As it's really easy to get magnets out of hard drives, there are a lot of these things in the surplus marketplace. However, Neodymium magnets are extremely powerful and should be managed with care. For instance, a large raw neodymium magnet will entice ferrous objects from further away than a magnet made from the exact same material in a more compact size.
A bar magnet has two magnetic poles, and its magnetic field is called a bipolar magnetic field.
When two bar magnets are held together, the magnet group has four poles, and its magnetic field is four.
Multistage magnetic fields are common, and any motor has a multipole magnetic field rotating inside it. The largest is the rotor of the permanent magnet stepper motor. Its surface has many magnetic poles, which can reach thousands.
Quadrupole magnet magnet. Also called focus on magnet is 2 meters long and weighs about 4 tons, quadrupole magnets is the international linear collider prophase preparatory programme, small aperture, the magnet processing difficulty is big, the magnetic field measurement are more demanding, for our small aperture on the design and manufacturing of spiral coil measurement, the stability and reliability of measurement system. Double aperture quadrupole magnet is BEPC Ⅱ collision zone first level is focused on the magnet, small volume, complicated structure, the magnet is one of the important equipment of BEPCII project, made in the world, there is no precedent, many parameters need to pass the correction unceasingly, manufacturing difficulty is big, high machining accuracy requirements.
